Ingestive behavior and physiological parameters of lactating goats fed diets containing detoxified castor cake.

This study aimed to evaluate the influence of the substitution of soybean meal (SM) by detoxified castor (DCC) by two alkaline products on the feeding behavior and physiological parameters of lactating goats of Saanen breeds and Anglo Nubian. The treatments consisted of three diets, with a standard formulation based on corn and FS and the others were formulated with detoxified castor by calcium hydroxide (Ca(OH)2 DCC) and another by sodium hydroxide (NaOH) DCC, which were and isonitrogenous and isoenergic. There was effect of diets on the consumption of DM and NDFap (P<0.05), with lower values for the goats fed with NaOH DCC. There was no effect (P<0.05) of diets on the fill times, rumination, time in other activities and time in idleness, rumination efficiency of NDF and chewing time total were influenced (P<0.05) by the diets. The goats fed with diet the basis of SM presented a higher heart rate and increased rectal temperature. When used in the composition of diets for lactating goats, the detoxified castor with sodium hydroxide leads to the reduction of intake DM, as well as the NDF, but both pies do not adversely affect the physiological parameters of goats.
